I'm quite sure I'll see several limits to the exponential growth in my
lifetime (probably the next 50 years), at least I already experience one
(probably temporal) limit: clock frequency didn't go up much the last 5
years. There however is a way to get more power out of computers: write
better software. It is amazing what vintage computer fans get out of
ancient designs. We are used to write software for computers that get
faster and have more memory, so we write a lot of slow, bloated
Due to the fact that single-threaded CPUs don't get (significantly)
faster anymore, we probably should start right now: Use better algorithms
to make single-threaded programs faster.
